Raw data of watchlist substances analysed in surface water in Luxembourg

Analysis of watchlist substances in surface waters are carried out at a frequency of 4 times per year at two representatif surveillance stations in Luxembourg. The chemicals included in the watchlist are determined on a EU level and include chemicals that potentially pose a significant risk to the aquatic environment but for which insufficient data exist to determine the actual risk posed by these substances.
The first watchlist (EU 2015/495; https://eur-lex.europa.eu/eli/dec_impl/2015/495/oj) was analysed from January 2016 until April 2018.
The second watchlist (EU 2018/840; https://eur-lex.europa.eu/eli/dec_impl/2018/840/oj) was analysed from July 2018 until January 2021.
The third watchlist (EU 2020/1161; https://eur-lex.europa.eu/eli/dec_impl/2020/1161/oj) was analysed from March 2021 until October 2022.
The analysis for the fourth watchlist (EU 2022/1307; https://eur-lex.europa.eu/eli/dec_impl/2022/1307/oj) started in January 2023 and is still ongoing.
